New drug trial targets annoying cough that Won't quit

This study is testing whether an experimental drug called HW091077 can reduce coughing in adults who have had a persistent cough for at least one year that hasn't responded to other treatments. About 180 participants will receive either the drug or a placebo for several weeks while researchers measure how often they cough and how it affects their daily life. The goal is to see if this medication can provide relief for people struggling with this frustrating condition.
